function Db_query ($qstring, $PRint =0) {

}

function Db_numrows ($qhandle) {
Return only if Qhandle exists, otherwise 0
if ($qhandle) {
Return @mysql_numrows ($qhandle);
} else {
return 0;
}
}

function Db_result ($qhandle, $row, $field) {
Return @mysql_result ($qhandle, $row, $field);
}

function Db_numfields ($lhandle) {
Return @mysql_numfields ($lhandle);
}

function Db_fieldname ($lhandle, $fnumber) {
Return @mysql_fieldname ($lhandle, $fnumber);
}

function Db_affected_rows ($qhandle) {
return @mysql_affected_rows ();
}

function Db_fetch_array ($qhandle) {
Return @mysql_fetch_array ($qhandle);
}

function Db_insertid ($qhandle) {
Return @mysql_insert_id ($qhandle);
}

function Db_error () {
return "\ n

". @mysql_error ()."

\ n ";
}

?>

The above describes the database abstraction Layer function library for MySQL, including the database function library aspects, I hope that the PHP tutorial interested in a friend helpful.
